String Theory and Nonrelativistic Gravity
September 19, 2019
We identify the proper geometry underlying non-relativistic string theory as 'String Newton-Cartan Gravity'. It has the distinguishing feature that one-dimensional foliation in Newton-Cartan geometry is replaced by a two-dimensional foliation on the target space. We discuss some basic properties of the string Newton-Cartan space-time, in particular it's behaviour under T-duality transformations. This leads to interesting non-relativistic conformal field theories at the boundary that have applications in condensed matter physics.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
